Abstract

Background It has been suggested that the process of discriminating between inner and outer experiences underlies auditory hallucinations (AHs). The aim of the present study was to investigate whether discrimination between imagined and performed action (i.e., action self monitoring) differed between schizophrenia patients with auditory hallucinations (AHs) and those without.Method Twenty-eight schizophrenia patients with AHs, twenty-six patients without AHs, and thirty-four healthy subjects were assessed with an action memory task. Simple actions were presented to the participant verbally (text) or non-verbally (icons). Some actions were physically performed and others were imagined. Following the learning phase, participants were presented with each action as well as new ones, were asked whether the action was presented verbally or non-verbally (action's presentation type discrimination), and whether the action was performed or imagined (self-monitoring). A confidence score related to self-monitoring responses was also obtained.Results Patients with AHs more often remembered imagined actions as performed than patients without AHs and healthy controls. Schizophrenia patients made significantly more incorrect responses in action presentation type discrimination than healthy controls. Self-monitoring errors were followed by high confidence ratings in the schizophrenia group. No differences between patients with and without AH in old/new recognition emerged.Conclusions Our study suggests that action self-monitoring deficits but not impairments in discriminating presentation type are related to AHs. In the schizophrenia group, action-self monitoring errors were associated with overconfidence.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Patients diagnosed with schizophrenia who experience AVHs are more likely to recall an imagined word as spoken or an imagined action as performed, compared to other patients and healthy controls.

    “It has also been shown that patients diagnosed with schizophrenia who experience AVHs are more likely to recall an imagined word as spoken (Franck et al., 2000) or an imagined action as performed (Gawęda et al., 2013), compared to other patients and healthy controls.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
